To all whom t may concern.'

lle it known that we, Louis H. Sironi? and .Ennns'r ll. Wirren, citizensof the United States, residing at Montrose, in the county of Montroseand State of Colorado, have invented new and useful Improvements inTire-Valves, of which the following is a specilieation.

This invention relates to inflation valves for the inner tubes ofpneumatic tires, and more particularly to the stem or casing of thevalve and the .means whereby the latter is secured in place on the wheelrim or folly.

rl`he invention has for its object to pro vide a fastening means bywhich the valve. stern can be easily and quickly removed when the tireis to be taken oit' the wheel, and repairs to the inner tube arefacilitated. The object stated is attained by means of a `novelcombination and arrangement of parts to be hereinafter described andclaimed, and in order that the same may be better understood, referenceis had to the accompanying drawing, specification. i

ln the drawing,

Figure 1 is a central vertical section showing the application oi theinvention, and

Fig. 2 is a cross section on the line 2 2 of Fig. 1.

Referring specifically to the drawing 5 denotes Va valve stem having anenlargelfnent or head 6 at its inner end, between which latter and aclamping plate 7 mounted on the stem, the tire tube 8 is held, the platebeing forced inward to clamp the tube by a nut 9 screwed on the stem,the inner portion thereof being extern ally screw-threaded for the nut,as shown at 10. 'llhese parts -are well known and constructed in theordinary manner; and a further description thereof is therefore notnecessary.A g

Urdinarily, the valve stem 5 also carries a loeltrnut engageable withthe felly of the wheel, on the inside thereof, for clamping the stem inplace. This lock nut must be removed from the valve stem before the tirecan be taken oft' the rim, and as this operation consumes some time, alocking` member has been devised which can be easily and quickly takenoff the valve stem or put hacithereon, said member being securely .heldin place 1without a threaded engagement with the valve stem. Thislocking member a collar which is in two sections denoted by the'reference characters 11 and 12, re-

` spectivel y, which forming a part of this pressing the two sectionstogether,

latter are hinged or pivoted together as shown at 13 in Fig. 2. The'hinge connection between the collar' sections is such that they may beopened up or spread for application to the valve stein 5 or removaltherefrom. Longitudinal movement of the collar on the valve stern isprevented by making the corrugated as shown at 14, and the inside of thecollar with rugations. Rotation of the vented by making the valve stemflat on diametrieally opposite sides and shaping the inside of thecollar correspondingly as shown in Fig, 2.

providing matching corcollar 1s pre- 'llhe collar section. 11 carries aspring latch 15 which snaps into a notch 16 in the collar section 12whenv the two sections are closed up around the valve stem 5, as shownin Fig. 2, whereby said sections vare securely locked in this position.

The meeting faces of the collar sections 11 and 12 are recessed to housea spring 17 which spreads or opens up the sections when the latch l5 isdisengaged.

The eorrugations 1li are Vshaped so that a wedging action betweenthe'same and the corrugations on the inside of the collar sections 11and 12 is produced when said sections ar'e closed up around the valvestem 5.

The collar sections 11 and 12 are reduced on top, as shown at 18, andthis reduced portion is externally screw-threaded to hold a dust cap1.9.

To remove 'the collar composed of the parts l1 and 12, the cap 19 isfirst taken 0H', and the latch 15 is disengaged, where upon the spring17 spreads the sections so that they may be slipped off thevalve stem 5endwise. he collar is put backen the valve stem in a similar manner, andupon latch. 15 snaps into the notch 16, whereupon the sections arelocked in closed position. It will therefore be seen that the collar canbe very easily and quickly taken ed' the valve stern or replacedthereon, and when in place it is securely held against longitudinal andturning movements on the stem.

The corrugated portion 14 of the valve stem 15 is smaller in diameterthan the inner threaded portion 10 which carries the nut 9, so that thelatter can also be quieltly taken off after it is run olif the portion10 up to the portion 14. As ordinarily constructed the valve stern isthreaded throughout its entire (itl outside of the latter i tltl thespring length, and the nut would have to he screwed veasier to ut heckthrouoh the hole in the tube after the repair is made, and theseoperations are effected Without danger of tearing the hele larger.`

Ne claim:

The combination, with e tire valve stein;

of e lock coller thereon and having an eX-' 1,eie,eee

ternally threaded outer portion, seid collar being, composed of hingedSections, ineens for holding seid sections closed around the stein,coperating ineens on the Stein and the collar for holding the letteragainst longitudinal movement on the stein, :nid :L dust Cep having e,threaded engugelneniiy with the aforesaid outer portion of the collar.

. In testimony whereof We a'ilix our Signum tures.
